The asymmetric unit of the title compound, [Cu(C4H8NO3)(C12H8N2)(H2O)]Cl·2H2O, contains a complex cation, a chloride anion and two water molecules. The CuII ion has a distorted square-pyramidal coordination geometry formed by one bidentate phenanthroline ligand, one O,N-bidentate dl-threoninate ligand and one apical water molecule. In the crystal structure, intermolecular O—H⋯O, N—H⋯O, N—H⋯Cl and O—H⋯Cl hydrogen bonds link the components into layers. A single weak intermolecular C—H⋯O interaction connects these layers into a three-dimensional network.
